I will need to follow up on this with you or your company to determine what additional equipment I need to make the system work.
I am working busy with construction right now of the porch which will be the platform for the solar collector.…"

I expect to install this unit when I finish building my back porch. A similar unit (owned by a friend) overheated and now leaks. I was told I needed an expansion tank and other controls to prevent this. Anyone have…"

Welcome, John. You have chosen a beautiful place to live.
Regarding your question on solar hydronic energy, I would first contact the Vancouver Renewable Energy Coop. Their site may have some value, but their staff have more experience than many in BC (sadly).
I am currently installing 10 PV panels on a mid-sized garden shed, and will then turn to the double (4'x16') solar-hydronic panels for the main house roof, which will feed down into a heat transfer tank to prewarm all water entering my combined DHW/Home heater. There are indeed surprisingly few people experienced in, let alone involved in, this kind of work. I also find that personally custom-built solutions and work-arounds vastly improve the performance of most off-the-shelf products.
Local, organic, rural, and/or urban, food production is a mainstay of life, and doing it well leads to wellness. From farm to kitchen, discussions relating to food--and the community arising around it--belong here.
If you have to leave your village, how will you get where you want to go? By car? Preferably not, both for your wallet and the earth’s sake. This category is for all discussions relating to how we all get around.
A human right? After food, most feel shelter is the most important necessity. A place of shelter is also the start of a community. This category is for all things relating to shelter, housing, affordable housing, homes, renewable heating systems, green buildings, heritage, and our built environment in general.
